Would load-average help you?

Or we could add a function that returns the amount of free VM on the
system.

Or you could arbitrarily limit the number of such processes to some
small value.

Please tell the details of how Emacs is notified about thumbnail
creation (or point to the code which does that), because I don't see
why you would need to explicitly trigger redisplay.  It should happen
automatically whenever the buffer contents changes in any way that
affects the displayed portion.
